Because you have not assigned any value to CurrTime or NewProfit

Check the returned value of ChartXYToTimePrice().
Return Value
Returns true if successful, otherwise false. To get information about the error, call the GetLastError() function.

They are supposed to be set by ChartXYToTimePrice().
Because you have not assigned any value to CurrTime or NewProfit
Keith Watford:
Because you have not assigned any value to CurrTime or NewProfit
But the values are there: 320 and 410, respectively. This values are meant to be converted into date and price and put in CurrTime and NewProfit by CBecause you have not assigned any value to CurrTime or NewProfit

Sorry, I had a few beers last night. I don't know what I must have been thinking!

Works fine for me:
int window = 0;
double NewProfit;
datetime CurrTime;
if(!ChartXYToTimePrice(0, 320, 410, window, CurrTime, NewProfit)) printf("Error: %i",GetLastError());
printf("NewProfit: %f",NewProfit);
printf("CurrTime: %s",TimeToStr(CurrTime));
double NewProfit;
datetime CurrTime;
if(!ChartXYToTimePrice(0, 320, 410, window, CurrTime, NewProfit)) printf("Error: %i",GetLastError());
printf("NewProfit: %f",NewProfit);
printf("CurrTime: %s",TimeToStr(CurrTime));

Thanks folks
The purpose seems defeated. I realize that the coordinates is for the objects on the window and not for the chart, while the price and date are for the chart and not for the objects on the window. They work similar to label and Text on the window. I want the coordinates that will move alongside the chart (price and dates) as well. Any suggestion please?
Thanks folks
I don't really understand what you are trying to achieve.
Some objects are set by time / price e.g. OBJ_RECTANGLE and OBJ_TEXT
Some objects are set by x / y e.g. OBJ_RECTANGLE_LABEL and OBJ_LABEL
You will need to pick the object type that suits your needs.
Perhaps a screenshot will help us to understand?
